I do Bullet Proof Tea with coconut oil. It can even be herbal tea with no caffeine. Often I don't eat until mid-afternoon. I can have a regular breakfast, then coast until dinner.

As I understand it, MCT oil doesn't get digested, just goes straight into the bloodstream.

Butter? Maybe when it come to good-fat-deprived organisms, it can do wonders
